HORACE T. ROBBINS, OF LOWELL, MASSACHUSETTS.

Specification of Letters Patent No. 8,807, dated March 16, 1852.

To all whom t may concern.'

Be it known that I, HORACE T. ROBBINS,

of Lowell, in the county of Middlesex` andA State of Massachusetts, have invented a new and useful improvement in the mode of holding or fastening the washers to the `spindles to prevent the washers turning around or working loose on the spindles in the throttle or other spinning where it as necessary to have washers for the bola-bins to run on; and I do herebydeclare that the same is fully described in the following specification and accompanying` drawings. letters, figures, and references thereof.

Of the said drawing, Figure l denotes a side view of a spindle having my improvement applied to it, Fig. 2 is a central and longitudinal section of it in which the spring, clasp or holder is represented as elevated above the washer so as to show the form of it, Fig. 3 is a tcp view of it, Fig. 4; is a longitudinal section taken so as to exhibit the clasp or holder as depressed, or driven down on to the washer as I design tohave it, so as to have the desired eifeet, and to have the .top of the spring, clasp or holder entirely belowv the top of the outer surface of the washer, leaving the outer surface of the washer so elevated that. the bobbin mav run on the outer surface of the wash-er without coming in contact with the spring, clasp or holder.

The nature of my invention consists in substituting a circular spring', clasp or holder a, Fig. L for the old mode of gluing',

. or cementing the washers b, to the button o,

which is driven tight on to the spindle d. By this arrangement I am enabled when one side of the washer has become glazed over or worn out,`to turn the washer over and use the other side of the washer', thus getting double the service from the washer which `is obtained in the old mode of cementing the washer to the button, besides holding the washer much more firm to the spindle. In the old mode the washer Z), is cemented i t0 the button c, which is driven tight on to the spindle CZ, as seen in Fig. 5 butthe large amount of friction from the bobbin frespindle d, which diiiculty is entirely overcome by the use of my spring, clasp or holder a, Fig. t the said spring, clasp or holder a, being made from a wire ring which has its two ends brought snug together so as toform a circular spring, the hole in the spring, clasp or holder a, being a trii'ie smaller than the spindle (Z, causes it when `driven on to the spindle d, to cling tight to the spindle CZ, and the spring, clasp, or holder a, having teeth e, e, &c. on the bottom as shown in Fig. l which b-eing drove down on to the washer Z), Fig. 4C and the washer b, driven in to the countersink or cavity in the button o, the teeth e, e, &c., stiel; in to the washer b, and hold it firmly to the spindle fZ, the said teeth are made by driving or pressing the wire ring in to a die of the proper form.

I do not intend to confine my invention to the applic-ation of the spring, clasp or holder a., to the countersunk button, as the same holder may be used witlra flat button by having the bobbin countersunk so as to let the bobbin down over the spring, clasp or holder, such in fact constituting the peculiar essence of my invention.

I therefore claim as my invention- The spring, clasp or holder a, or its equivalent either with, or wit-hout teeth in comused therewith substantially in the manner and for the purpose of holding the washer as specified.

In testimony whereof I have hereto set my signature this seventh day of November A. D. 1851.
